A quick and dirty client/server logger based on loguru and zmq for logging over a network.
Start the server, binding to suitable port, and then you can send messages from multiple clients over a network. The host name of the client machine is added into loguru's extra dictionary.
It is currently using pickle to serialise the log message. https://pypi.org/project/securepickle/ is used to (hopefully) prevent attackers modify the data. However, there are currently no other security considerations, so I still wouldn't use this on an untrusted network.
Example usage:
#server.py
from zmq_logger.LoggerServer import ZMQLogger
import sys
from loguru import logger
import time
if __name__ == "__main__":
"""
Simple test example, start the server for 600 seconds
"""
logger.info('Starting')
# change the hash to some private binary string
zmlog = ZMQLogger(hash=b"change me to something else")
# configure loguru to use our formatter. You need to do this, but this adds the client
# hostname to the message.
logger.configure(handlers=[{"sink": sys.stderr, "format": ZMQLogger.formatter}])
# start the logger thread
zmlog.start()
time.sleep(600) # for the demo, just sleep this thread for 600 seconds before closing
logger.info('Stopping')
# stop the logger thread.
zmlog.stop()
and
#client.py
from zmq_logger.LoggerClient import setup
from loguru import logger
import time
if __name__ == "__main__":
# this is a simple helper function that set up securepickle and configures the loguru handler
# to print to stderr and the remote server.
setup(host="tcp://127.0.0.1", port=9999, hash=b"change me to something else")
for p in range(20):
# log a message and send to the server. Note,
logger.info(f"Logging from client {p}")
time.sleep(1)
